Chick fil A is the only fast food to date that I can eat with celiac or want to eat in general! Their grilled nuggets are GF, some of their sides including the waffle fries are GF and cooked in separate fryer as far as I know. They also offer some GF salads. They also offer GF buns. On the spectrum of sensitivity to gluten I’m fairly sensitive and have never gotten sick after eating here. Most the dipping sauces are GF. You have to do your homework online beforehand if you’re unsure.
